What should I know about allergietest?

Allergy tests can be useful, but their reliability depends on the type. Clinically established methods include skin prick tests and specific IgE blood tests (e.g., for pollen, foods). These indicate sensitization, not necessarily clinical allergy – diagnosis requires correlation with symptoms and sometimes provocation. Direct-to-consumer tests (e.g., IgG food sensitivity panels or genetic allergy risk scores) are often poorly validated. IgG tests for food intolerances are not recommended by medical societies because they yield many false positives and may lead to unnecessary dietary restrictions. Genetic tests (e.g., HLA variants) have weak predictive power. If you have genuine allergy symptoms, see an allergist. Self-tests cannot replace a medical workup. Evidence: standard tests are well-supported; DTC and IgG tests are largely marketing-driven or lack solid evidence.
